TECHNICAL FIELD

The present invention is directed to control architecture and, more particularly, to control architecture for use with transport systems for moving articles from one location to another location.

BACKGROUND OF THE INVENTION

Conventional transport systems used in industry for moving articles from one location to another typically comprise rotary dive systems having mechanical components such as gears, shafts, keys, sprockets, chains and belts, rollers, and the like for moving an axis or transport element (such as a conveyor belt) that transports articles along a predetermined path or track. The rotary drives are controlled using a computer control system that operates control software to permit an operator to enter into the control system various command parameters that are used to create a motion profile for the transport element being utilized by the particular transport system.

Transport systems, such as controlled motion systems utilizing linear drives, are used in a wide variety of processes (e.g. packaging, assembly automation, processes involving use of machine tools, etc.) and provide the advantage over conventional rotary drive systems of increasing both the speed and the flexibility of the process. In particular, linear motors operate as magnetic drives creating a changing magnetic field to directly transport the axis or transport element along a defined track, thereby eliminating various conventional axes, such as gear heads, shafts, keys, sprockets, chains and belts, used with traditional rotary drive systems. The reduction of mechanical complexity over rotary drive systems provides both reduced cost and increased speed capability by virtue of reduced inertia, compliance, damping, friction and wear. Further, controlled motion systems utilizing linear drives also provide greater flexibility than conventional rotary drive systems by allowing one or more individual axes or transport elements to be independently controlled while transporting articles along an entire track.

Unlike conventional rotary drive systems that have a single drive for energizing an axis or transport element for moving articles along a track, linear motion systems typically comprise interconnected track sections wherein one or more drives are electrically coupled to a plurality of transport elements and have individually controlled coils that cooperate with one or more control units to energize or de-energize the coils to create magnetic fields effective for providing controlled motion of each transport element traveling along the track. Such systems also employ a plurality of linear encoder readers spaced at fixed positions along the track and sensors mounted on each transport element that cooperate with the linear encoder readers to provide signals to a control unit for use in determining the position of each transport element along the track.

Typically, control architecture utilized for conventional linear motion transport systems include an input device, such as a keypad, whereby an operator enters command parameters (such as the particular track identification, the speed that a transport element or axis travels along the track, stop and start locations, and time parameters for the transport element) into a control unit, such as a convention computer system, to create a motion profile. The control unit functions to operate software specifically designed for controlling the operation of the particular linear transport system being used. Unfortunately, the use of such specifically designed software for controlling a particular linear motion transport system often requires the operator to learn new software protocols for each new designed software package. Thus, for example, an operator using a plurality of different transport systems must learn to operate a number of different software packages.

Conventional control systems are typically designed for transport systems where transport elements do not move from one drive section to another dive section, such as when transport items are traveling along different tracks or move from one track to another track. Accordingly, a need exists for control architecture that can control transport elements moving from one drive to another drive, such as linear motion systems when a transport element moves from traveling along one track to traveling along another track or when it is desirable to control transport elements traveling along different tracks using a single control system.

Another problem often encountered with the use of specifically designed control software is that it is often desirable to have a transport system of one manufacturer coupled to the same control system being used by a transport system of another manufacturer. Accordingly, such a combined system eliminates the need for an operator to use two different control software packages thereby decreasing the cost and complexity of the transport systems. Further, the use of transport systems from different manufacturers often requires the operator to use more than one control system (or software package) or learn the operation of different software packages thereby increasing the training time for the operator and decreases the efficiency of the overall operation. In addition, the difficulty of integrating two different transport systems having two different control systems significantly increases the complexity and cost of the overall operation.

Accordingly, it is desirable to have a control architecture effective for controlling a transport system that has similar programmatic features as used in conventional single drive systems, such as rotary drive systems. It is also desirable to have control architecture effective for controlling a transport system that allows an operator to use traditional software for controlling conventional single drive transport systems; that can be used to control a transport system having more than one drive system; that can be used with linear drive systems whereby transport elements operate on different tracks; that allows additional independent drive systems to be easily incorporated into the transport system; allows a single control system to operate more than one transport system or a transport system having more than one track; and allows an operate to use traditional control software for a transport system having a single transport element for controlling a transport system having more than one transport element.

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to control architecture for transport systems for receiving articles at one location and transporting the articles to another location. In describing the preferred embodiments of the invention illustrated in the drawings, specific terminology will be resorted to for the sake of clarity. However, the invention is not intended to be limited to the specific terms so selected, and it is to be understood that each specific term includes all technical equivalents that operate in a similar manner to accomplish a similar purpose.

Referring to FIGS. 1, 2 and 3, a schematic representation of typical transport system 100 for moving articles from one location to another location having a preferred embodiment of the control architecture of the subject invention 102 is shown (FIG. 4). In a preferred embodiment of the invention the transport system 100 is a linear magnetic drive system preferably includes a track 104 formed from interconnected track sections 106 having a drive system 108 comprising activation elements 110, such as a plurality of electromagnet coils 112, that operate by creating electromagnetic fields (FIG. 2). Coupled to the track 104 is one or more axis or transport elements 114 mounted to permit each transport element 114 to travel along the track 104 (FIG. 3). Each transport element 114 is movable independent of each other and includes reaction elements 116 preferably comprising one or more magnets 118, such as rare-earth permanent magnets, which cooperate with the activation elements 110 positioned along the track 104 to produce relative movement there between when the activation elements 110 are energized and/or de-energized. In a preferred embodiment, as shown in FIG. 4, the control architecture 102 includes a gateway 120 that is electrically coupled to the drive system 108 to operate and control the motion of each transport element 114. Each transport element 114 further includes a control sensor 122 (FIG. 3) that provides a signal for use by the gateway 120 for operating the drive system 108 by energizing and/or de-energizing the activation elements 110 positioned along the track 104 thereby producing controlled movement of each transport element 114.

In a preferred embodiment the control architecture 102 includes a computer system 124 or other similar system effective for implementing and operating control system software 126 that performs to permit an operator O to input commands and any desired protocols (such as the particular track identification, the speed that a transport element or axis travels along the track, and stop and start locations and length of time for the transport element) into the control architecture 102 to create a motion profile 128 for a transport element 114. The computer system 124 preferably includes a controller 130 having a processor and a memory 132 for operating the system software 126. It should be understood that the processor and memory 132 can comprise various computing hardware such as central processing units (CPU's), graphics processing units (GPU's), digital signal processors (DSP's), microprocessors and/or other such data processing devices. The computer system 124 further comprises other devices, such as a suitable input device, like a keypad, touch screen, or any other suitable input device 134 that can accept information from an operator O. The processor and memory 132 can include any of the usual devices used for the storage of data, such as computer hard drives, floppy discs, binary codes, optical bits, mechanical scribes, magnetic tapes, compact discs, digital audio tapes, analog tapes, vinyl discs, and any device or devices capable of storing data. It should be understood that the computer system 124 can include any combination of the above components, or any number of different components, peripherals, and other devices. Preferably, the computer system 124 operates under the control of an operating system, such as the WINDOWS operating system developed by Microsoft Corporation or the MACINTOSH operating system developed by Apple Computer Corporation. It should be understood, however, that other operating systems could be utilized to implement the control system software of the computer system of the present invention.

Referring to FIG. 4, gateway 120 of the control architecture 102 operates to receive the motion profile 128 from the control system software 126 of the computer system 124. As shown, the gateway 120 operates the drive system 108 by energizing or de-energizing the activation elements 110, such as individual electromagnetic coils 112, positioned along the track 104 create a moving magnetic field to directly move one or more of the axes or transport elements 114 along the track 104 in accordance with the motion profile 128.

Preferably, gateway 120 includes a controller 136 and a processor and a memory 138 that operates the gateway drive software 140. It should be understood that the processor and memory 138 can comprise various computing hardware such as central processing units (CPU's), graphics processing units (GPU's), digital signal processors (DSP's), microprocessors and/or other such data processing devices. The processor and memory 138 can include any of the usual devices used for the storage of data, such as computer hard drives, floppy discs, binary codes, optical bits, mechanical scribes, magnetic tapes, compact discs, digital audio tapes, analog tapes, vinyl discs, and any device or devices capable of storing data. Preferably, the processor and memory operates under the control of an operating system, such as the WINDOWS operating system developed by Microsoft Corporation or the MACINTOSH operating system developed by Apple Computer Corporation. It should be understood, however, that other operating systems could be utilized to implement gateway drive software of the present invention.

In a preferred embodiment, the computer system 124 is electrically coupled to the gateway 120 to permit communication there between. Referring to FIG. 4, an operator enters into the computer system 124, using the conventional input device 134, the various instructions and protocols needed to create a motion profile 128 for each transport element 114 for the particular transport system being utilized. Such instructions and protocols can include information such as the particular transport system and the particular axis or transport element(s). In a preferred embodiment of the invention, the control system software 126 is traditional software selected by the operator for controlling a transport system 100 having a particular drive system 108, such as a linear drive system comprising a single track and a single transport element operating thereon or a conventional rotary axis system having a single transport element. The computer system 124 being in electrical communication with the gateway 120 operates to transfer the motion profile 128 created by the control system software 126 using the instructions and protocols inputted by the operator using the input device 132 of the computer system 124. The gateway drive software 140 utilizing the motion profiles 128 operates to identify the particular transport system 100, the particular drive system 108 and the axis or transport element 114 and identifies and activates the identified drive system 108 (such as a particular linear magnetic drive system by energizing and de-energizing the activation elements) to direct and move one or more of the transfer elements along a track in accordance with their motion profile 128.

In a preferred embodiment the transport system 100 includes a positioning system 144 for determining and monitoring the position of each transport element 114 traveling along the track 104. In a preferred embodiment, the positioning system 144 is of the type typically used for a linear motion system (as shown) and includes “incremental absolute” position sensors or encoders 146 and counter 148 that operates by sensing and counting incremental pulses (or digitize sine/cosine signals to create these pulses) to count up or down after a transport element 114 travels past a reference point. It should be understood that the positioning system 144 can be used as part of a linear motion system having a single axis or transport element or as part of a linear motion system having multiple axis or transport elements and operates to track the position of each such transport system as it moves along the track. The positioning system 144 is electrically coupled to the gateway 120 and provides a position signal 150 for each transport element 114. It should also be understood however that other positioning systems that may be used for sensing the position of transport elements 114 moving along a linear motion system can also be utilized for such systems. The gateway 120 operates to use the position signal 150 for each transport element to 114, such as through a conventional feedback control loop, to ensure that the transport elements 114 are operating (traveling along the track or path) in accordance with the motion profile 128 as well as to ensuring the one transport element does not interfere with the movement of another transport element. For an example, the gateway cooperates with the positioning system to calculate time and position of each transport element in association with their motion profiles and operates to adjust the motion profiles to ensure that the transport elements traveling along a track do not make contact with other transport elements or otherwise restrict movement of another transport element.

In a preferred embodiment of the invention the transport system 100 is a linear drive system comprising a track 104, more than one axis or transport elements 114, and a drive system 108 having one or more activation elements 110 positioned along the track 104, and one or more encoders 146 positioned along the track 104. Each transport element 114 is movably attached for traveling along the track 104. Referring to FIG. 5, in operation, the control architecture operates such that the system software receives information, including instructions and/or protocols, from an operator (step 200) and creates a motion profile for directing the operation of each transport element (step 202). It should be understood that the control system software is traditional software for use in conventional single drive transport systems, such as conventional rotary drive transport systems, having a single transport element. In a preferred embodiment the control system software is conventional control system software for controlling more than one rotary drive system each having a single transport element. An operator using the control system software inputs control parameters and other information for creating a motion profile for each transport element operating on each transport system. Once the instructions and/or protocols are entered into the computer system by the operator, the system software operates to create and direct a motion profile to the processor and memory of the gateway (step 204). The gateway drive software is configured to receive and utilize the motion profile and determines the particular transport system and/or drive system (step 206) and operates the gateway to energize and de-energize the identified drive system to move each transport element in accordance with its motion profile (Step 208). It should now be understood that unlike conventional control systems for single drive transport systems, such as conventional rotary drive systems, in which the transport system has a single transport element controlled by a single drive, the control architecture of the subject invention allows an operator to control one or more transport systems each having one or more transport elements operating thereon.

In a preferred embodiment of the invention the drive system includes a positioning system that operates to provide a signal to the gateway which functions as a feedback control loop for use by the gateway drive software for ensuring that each transport element is operating in accordance with its motion profile (step 210). It should also now be understood that the positioning system further permits the gateway drive software to monitor the location of each transport element traveling along each transport system and operates to ensure that the transport elements do not contact another transport element or otherwise interfere with the movement of another transport element.

For another illustrative example of a preferred embodiment of the method of the subject invention, the identified drive system is a conventional linear motion drive system. The gateway control software operates to energize and de-energize the activation elements along the track that cooperate with the reaction elements on the individual transport elements to move the each transport element along the track in accordance with the motion profile for the particular transport element. The positioning system cooperates with the control sensor on each of the transport elements to provide a signal to the gateway effective for monitoring the location of each transport element and ensure that the transport elements are directed in accordance with the motion profile without interfering with another transport element.

It should now be apparent to one skilled in the art that the control architecture of the subject invention operates to allow a motion profile to be created using conventional control system software for a transport system having a single transport element and using a conventional single drive (such as a rotary drive system) to create motion profiles for transport systems having more than one drive and/or more than one transport element. In operation, the gateway of the subject invention operates to receive the motion profile for each transport element, determines the drive system for driving each transport element, and controls the drive system in accordance with the motion profile for each transport element. Accordingly, it should now be apparent to one skilled in the art that the control architecture of the subject invention operates such that it appears to the operator that each transport element is operating on its own independent drive system thereby allowing the operator to create motion profiles for multiple drive and/or multiple independently controlled transport elements by input information using conventional system software for controlling a single drive, signal transport element systems.

In another preferred embodiment of the invention the transport system comprises a transport system 100 having a drive system 108, such as a linear drive system, having more than one track 104 and activation elements 110 positioned along each track 104, and one or more encoders 146 also positioned along each track 104. One or more transport elements 114 are movably attached for traveling along each track 104. Referring to FIG. 7, in operation, the control architecture operates such that the control system software receives information, including instructions and/or protocols for directing the operation of each transport element from an operator (step 200) and creates a motion profile for each transport element (step 203). It should be understood that the control system software is traditional software for use in conventional single drive transport systems, such as conventional rotary drive transport systems or a single linear dive system, having a single transport element. Accordingly, the operator inputs instructions and/or protocols into the control system software as if each transport element was operating on a separate single drive transport system having a single transport element. Once the instructions and/or protocols are entered into the computer system by the operator, the control system software operates to communicate the motion profiles to the gateway (step 204). The gateway drive software is configured to receive and utilize the motion profiles and operates to select the particular transport elements (step 206) and energize and de-energize the activation elements positioned along the track that cooperates with the reaction elements on the individual selected transport elements to move each transport element along the track (step 208). The positioning system for each linear motion drive system cooperates with the control sensor on each transport element to provide signals to the gateway to track the location of each transport element and ensure that the transport elements are directed in accordance with their motion profile (step 210). It should now be understood that the control architecture of the subject invention operates such that the gateway can direct an individual or a plurality of independent or dependent transport systems based on the motion profile.

It should now be apparent to one skilled in the art that the control architecture of the subject invention can be used in conjunction or as part of a transport system comprising one or more linear drive systems and one or more rotary drive systems, or any combination thereof. Further, the control architecture of the subject invention can comprise two separate components, such as a separate computer system for operating the control system software and a separate gateway for operating the gateway drive software or can comprise a single component operating both the control system software and the gateway drive software such that a single processor or multiple processors operating both the control system software and the gateway drive software. It should also now be apparent to one skilled in the art that the control architecture of the subject invention can incorporate traditional software typically used for inputting and controlling conventional single drive systems, such as a conventional rotary drive system, to allow an operator to input information and/or instructions. Accordingly, an operator using traditional control software for a signal drive system can input control protocols and instructions for creating a motion profiles for a drive system having a plurality of transport elements. In another preferred embodiment of the invention the operator enters specific drive (or drive system) identification and information directed to that specific drive. The operator can continue adding information for each specific drive identified to be within a specific transport system until all the information has been entered. The system software then operates to create a motion profile and transmits the motion profile to the gateway. The gateway then operates to identify the particular drive system and directs the transport element(s) identified for each specific drive in accordance with the motion profile. It should now be apparent that the computer software operates as if there is one transport element for each drive system while the gateway permits multiple transport elements to operate on one or more drive systems.

It should now be apparent to one skilled in the art that the control architecture of the subject invention operates to allow a motion profile to be created for a transport system having more than one drive and/or more than one track and/or more than one axis or transport element using conventional software for creating a motion profile for a transport system comprising a single rotary drive system, or a multiple rotary drive system, or a linear drive system having a single track and one or more axis or transport elements moving along the track, or a linear drive system having more than one track with one or more axis or transport elements moving along each track.

It should now be apparent to one skilled in the art that the control architecture of the subject invention is effective for controlling a transport system that has similar programmatic features as used in conventional single drive systems having a single transport element. It should also now be apparent that the control architecture of the subject invention is effective for controlling a transport system that allows an operator to use traditional software for controlling conventional single drive, single transport element systems; can be used to control a transport system having more than one drive system; can be used with linear drive systems whereby transport elements operate on different tracks; that allows additional independent drive systems to be easily incorporated into the transport system; allows a single control system to operate more than one transport system or a transport system having more than one track; and allows an operate to use traditional control software to control one or more transport elements. Accordingly, in a preferred embodiment the control architecture of the subject invention operates such that linear drive systems (having one or more transport elements moving thereon) are virtualized to look and controlled such that the perceived view of the operator is such that it appears to be one or more rotary drive systems (one system for each transport element).
